Może mi ktoś powiedzieć co jest źle w tym kodzie? Npc się pojawia lecz nie reaguje na polecenie kupna np: jak pyta na ile dni pacc opisuje 7 itp a on nic tak samo z promocją. Co poszło nie tak?

A o to kod:

data/npc/Premmy.xml

<?xml version="1.0" encoding="UTF-8"?>
<npc name="Premium" script="data/npc/scripts/promotion.lua" autowalk="1" floorchange="0">
    <health now="100" max="100"/>
    <look type="153" head="77" body="119" legs="0" feet="0" addons="1"/>
    <parameters>
        <parameter key="message_greet" value="|PLAYERNAME| I can sell you Premiums and Promotions"/>
        <parameter key="message_needmoremoney" value="You do not have enough money."/>
        <parameter key="message_decline" value="Maybe next time?"/>
    </parameters>
</npc>

add it in the end (go to one enter) data/npc/lib/npcsystem/modules.lua

    if(cid ~= npcHandler.focus) then
            return false
    end
    if getPlayerPremiumDays(cid) <= 350 then
        if(doPlayerRemoveMoney(cid, parameters.cost) ~= TRUE) then
            npcHandler:say('You do not have enough money!')
